Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste decomposition apparatus for fermenting and decomposition of organic waste such as manure discharged from livestock, food waste discharged from households, and sewage sludge.

[0002]

2. Description of the Related Art As a waste decomposition apparatus for treating organic waste such as manure and food waste, for example, as shown in FIG.
A structure in which the organic waste M stored in the storage tank 50 is promoted to be fermented and decomposed by scooping and stirring the organic waste M by the stirrer 51 is often adopted. In FIG. 6, the agitator 51 includes a sprocket 52 and a sprocket 52, which are vertically opposed to each other.
By rotating and driving the endless strip 54 such as a chain wound between three, the organic waste M in the storage tank 50 is scraped up and stirred by the flight member 55 projecting outside the endless strip 54. This is the configuration. When the agitator 51 moves in the storage tank 50 by the traveling carriage 56 running on the storage tank 50, the organic waste M in the storage tank 50 is evenly stirred up and stirred. Further, in the agitator 51, it is general that the endless strip 54 is rotationally driven so as to rise on the front side in the traveling direction and descend on the rear side in the traveling direction.

[0003]

In the waste decomposition apparatus shown in FIG. 6, the scraped organic waste M is continuously supplied from the front side in the traveling direction to the space formed on the rear side in the traveling direction of the stirrer 51. Are being transferred. However, when the organic waste M on the rear side in the traveling direction is also scraped up and stirred, the flight member 55 presses the organic waste M against the bottom portion 50a of the storage tank 50, so that the rotation resistance of the endless strip 54 is increased. Will become very large and will cause a malfunction. In addition, cost increase is inevitable due to the increase in size of drive equipment such as a drive motor, and since the agitator itself can withstand a large drive force, size increase of each member is unavoidable, resulting in miniaturization and low cost. There is a problem that it is difficult to convert.

In view of the above problem, for example, a shield plate is arranged close to the moving path of the flight member 55 on the rear side in the traveling direction of the stirrer 51 to prevent the contact between the flight member 55 and the organic waste M. It is possible to take measures such as However, this inevitably increases the cost due to the increase in the size of the stirrer 51 and the size of the traveling carriage 56 due to the increase in the weight of the stirrer 51. In addition, the agitator 51 and the traveling carriage 56
However, if the size of the storage tank 50 is increased, it takes much time and labor to change the direction in the storage tank 50, and the design of the storage tank 50 is limited.

By the way, as a technique capable of preventing the agitating and stirring of organic waste on the rear side in the traveling direction without installing the shielding plate, for example, there is a waste decomposition treatment apparatus described in JP-A-9-253615. This device rotates the endless strip wound between the upper and lower sprockets,
The operation of scraping up and stirring the organic waste in the storage tank by the flight member projecting outside the endless strip is the same as the device illustrated in FIG. 6, but the rotatable L-shaped flight member is used. On the front side in the traveling direction of the stirrer, the flight member moves while sliding on the guide frame arranged along the movement path of the flight member, so that the L-shaped piece of the flight member moves forward in the traveling direction. Ascending while maintaining the protruding state, when moving to the rear side in the traveling direction at the upper part of the stirrer, one L-shaped piece of the flight member comes into contact with the abutting piece fixed to the stirrer to project By pushing and rotating to a position where the above is eliminated, a rear surface that closes the rear side in the traveling direction of the stirrer is formed. Further, in the lower portion of the stirrer, the L-shaped piece is pushed outward by the rotation of the flight member due to contact with a projecting member installed inside the stirrer, and the L-shaped piece is projected and the front side in the traveling direction is set. Move up.

In this apparatus, since the rear surface of the stirrer is formed by the flight member, it is possible to prevent the agitating and stirring of the organic waste on the rear side in the traveling direction without separately installing a shielding plate. However, in this device, there is no means for restricting the rotation of the flight member that has passed through the abutting piece to the outside (rear side in the traveling direction), so that the organic waste and the flight member accumulated on the rear side in the traveling direction of the stirrer If the contact is not sufficient, the flight member rotates and the other piece protrudes to the outside, and it is not possible to reliably prevent the organic waste from entering the agitator from the rear surface side. In addition, in this device, vibration generated during operation is large due to the impact force generated when the flight member comes into contact with the abutting piece and the projecting member above and below the stirrer, and the scraped organic waste is removed from the flight member. There is a problem that the spillage falls and the efficiency of the frying and stirring deteriorates after all. In particular, the impact force generated by the contact between the contact piece and the flight member at the upper part of the stirrer directly affects the spillage of the organic waste transferred to the upper part of the stirrer by the flight member. The organic waste in the storage tank is fermented and decomposed by agitating several times, and moreover,
Each time the stirrer stirs and stirs, the fermentation and decomposition proceed sequentially and systematically while transferring to the rear side in the traveling direction of the stirrer (using the conveyor, for example, next to the moving path of the stirrer). Therefore, if organic waste frequently spills during frying or during transfer, the plan of fermentation decomposition in the entire storage tank will be misaligned, and the fermentation decomposition efficiency will decrease and There arises a problem that it causes variations in the quality of the obtained compost and the like. Further, if the rotation speed of the endless strip is limited to suppress vibration, the efficiency of the stir-frying stirring cannot be improved due to this as well.

Further, when the organic waste spilled from the flight member enters the inside of the stirrer, the device inside the stirrer may be caught and cause a failure.
The flight member of the device described in JP-A-9-253615 is
While passing through the upper part of the stirrer, one L-shaped piece turns from the front side in the direction of travel around the upper part of the stirrer along the sprocket to reach the rear side in the direction of travel while projecting outward from the endless strip. Is in a standing state, and in particular, organic waste is likely to spill and the fallen organic waste is likely to enter the stirrer. Especially, the flight member passing near the upper sprocket is directly affected by the vibration generated near the contact piece, and in some cases, a large amount of organic waste may fall into the stirrer. In other words, in this apparatus, even with the stirrer, it is possible to use
The device described in 53615 does not provide a fundamental solution to the problem.

The present invention has been made in view of the above circumstances. (1) A rail engaging portion provided on the inner surface of the flight member facing the inside of the stirrer, and a rail provided on the stirrer. By contacting and engaging with each other, it is possible to realize the projection of the flight member on the front side in the traveling direction of the stirrer and the formation of the rear surface of the stirrer by eliminating the protrusion of the flight member on the rear side in the traveling direction with a very simple and low-cost configuration. (2) Most of the moving path of the rail engaging portion due to the rotational driving of the endless strip can be a rail, and further, depending on the contact between the rail and the rail engaging portion or the engaging condition,
Since the attitude of the flight member can be controlled, it is possible to reduce the vibration generated during the driving due to the rotational drive of the endless strip. (3) The vibration prevention in (2) above scoops up in the forward direction. Prevention of spillage of organic waste from flight members can be easily achieved. (4) By forming the rear surface of (1) above, it is possible to effectively increase the rotation resistance of the endless filament and to infiltrate the organic waste into the stirrer. It is an object of the present invention to provide a waste decomposition apparatus that can be effectively prevented.

As shown in FIGS. 4 and 5, the rail engaging portion 17 provided on the inner surface side of the flight member 10 facing the outer surface is separated from the pivot shaft 14 of the flight member 10. An arm 18 obliquely projecting from the end toward the pivot 14 and a rotatable roller projecting from the side of the tip of the arm 18 in the protruding direction with a rotation axis parallel to the pivot 14. 19 and. The arm 18 is firmly fixed to the flight member 10, and the inclination angle with respect to the flight member 10 is constant.

As shown in FIGS. 1 and 4, on the front side in the traveling direction of the agitator 5, the endless strip 8 is stretched between the upper and lower sprockets 6 and 7 to form a straight line. The flight member 10 that rises on the front surface side of the stirrer 5 by the rotational drive of the endless strip 8 has a front rail 20 provided inside thereof along the movement trajectory of the pivot shaft 14 by the rotational drive of the endless strip 8. When the roller 19 of the rail engaging portion 17 is brought into contact with the front side of the stirrer 5 in the traveling direction, the stirrer 5 is projected to the front side in the traveling direction, and the stirrer 5 is moved while maintaining the protruding state. It is like this. Therefore, on the front side in the traveling direction of the stirrer 5, the organic waste M is scraped up and transferred upward by the flight member 10 that is moved upward while maintaining the protruding state. The front rail 17 is fixed to the stirrer body 12.

As shown in FIGS. 1 and 4, even at the rear side of the stirrer 5 in the traveling direction, the endless strip 8 has upper and lower sprockets 6,
It is stretched between 7 to form a straight line. The flight member 10 that descends on the rear surface side of the stirrer 5 by the rotational drive of the endless strip 8 has the rear surface side rail 2 disposed inside thereof along the movement locus of the pivot shaft 14 by the rotational drive of the endless strip 8.
1, the rail engaging portion 1 from the front side in the traveling direction of the stirrer 5.
When the roller 19 of No. 7 is engaged, the state of being accommodated in the flight member accommodation space 16 is maintained. On the rear side in the traveling direction of the stirrer 5, the outer surfaces of the fixed plate 13, the flight member 10, and the closing plate 15, which are the opposite sides facing the stirrer body 12, are continuously arranged substantially flush with each other and are substantially sealed. Forming a rear surface. Therefore, on the rear side in the traveling direction of the stirrer 5, the organic waste M is not scooped up by the flight member 10, and the contact resistance of the fixed plate 13, the flight member 10, and the closing plate 15 with the organic waste M is kept low. The rotation resistance of the endless strip 8 hardly increases. Further, the rear surface formed by the fixing plate 13, the flight member 10, and the closing plate 15 can prevent the organic waste M from entering the inside of the stirrer 5 from the rear side in the traveling direction. The rear rail 21 is fixed to the stirrer body 12.

The flight member 10 moved upward along a front rail 20 extending straight between the upper and lower sprockets 6 and 7 has an upper engagement transition portion 22 provided near the upper sprocket 6. The contact from the front side in the traveling direction with respect to the front rail 20 is changed to the engagement from the front side in the traveling direction with respect to the rear rail 21 via the. The upper engagement transition portion 22 extends continuously from the upper end of the front rail 20 and the horizontal maintenance rail 23 formed to extend continuously from the upper end of the front rail 20. The rail engaging portion 17 (specifically, the roller 19) of the flight member 10 which is formed as described above and has moved along the horizontal maintaining rail 23 is provided on the front side of the rear side rail 21 in the agitator advancing direction. And an upper guide rail 24 for guiding.

The horizontal maintaining rail 23 is provided inside the stirrer 5 with respect to the portion where the movement locus of the pivot 14 due to the rotational driving of the endless strip 8 is curved along the outer circumference of the upper sprocket 6. It is curved concentrically around the rotation center of the sprocket 6, and between the movement trajectory of the pivot 14 and the horizontal maintenance rail 23, the radius of rotation of the roller 19 about the pivot 14 (more specifically, the roller). A distance substantially equal to the radius of gyration of the lower end of 19 is secured. The flight member 10 moves while the roller 19 of the rail engaging portion 17 is brought into contact with the horizontal maintaining rail 23, so that the flight member 10 projects toward the front side in the traveling direction of the stirrer 5, that is, a substantially horizontal posture. While maintaining the above, the front side rail 20 side is reached above the upper sprocket 6. Therefore, the flight member 10 is scraped off from the front side in the traveling direction of the stirrer 5 and
The organic waste M on top of the
It is transferred to the upper sprocket 6 with almost no falling from 0. Further, by preventing the spillage, it is possible to prevent a large amount of dropping into the stirrer 5 and the like.

Specifically, in the flight member 10 of the flight unit 9 that moves on the front rail 20 and the horizontal maintenance rail 23, the roller 19 at the tip of the arm 18 of the rail engaging portion 17 is from the front side in the traveling direction of the stirrer 5. Vertically below the pivot 14 that contacts the front side rail 20 and connects the fixed plate 13 (the direction of the straight line connecting the rotation centers of the upper and lower sprockets 6 and 7 is referred to as the "vertical direction in the stirrer 5", Then, when it means "downward in the vertical direction of the stirrer 5 of the pivot 14"), the horizontal state is maintained. The flight member 10 of the flight unit 9 moving on the front rail 20 moves while the roller 19 is in contact with the front rail 20 from the front side in the advancing direction of the agitator 5, so that the agitator 5 of the roller 19 with respect to the pivot shaft 14 moves.
Since the vertical positional relationship in the vertical direction is maintained, this causes the stirrer 5 to move upward while maintaining the protruding state to the front side in the traveling direction.

The movement trajectory of the pivot 14 and the horizontal maintenance rail 23
The difference between the moving loci of the pivots 14 and the bending radii about the respective bending centers of the horizontal maintaining rails 23, that is, the bending radii about the rotation centers of the sprockets 6, is The radius of gyration of the roller 19 around 14 (specifically, the radius of gyration of the lower end of the roller 19) is substantially matched. Therefore, even if the roller 19 of the flight unit 9 gets on the horizontal maintenance rail 23 from the front rail 20 and starts to move along the horizontal maintenance rail 23, the roller 19 is vertically downward in the agitator 5 with respect to the pivot shaft 14. The lower end of the flight member is maintained, and the flight member 10 is moved while being kept horizontal.

The roller 19 of the rail engaging portion 17 of the flight member 10 that has moved along the horizontal maintaining rail 23 is located near the uppermost portion of the upper sprocket 6.

In the flight unit 9 which moves along the upper guide rail 24, the pivot shaft 14 and the roller 19 are positioned on a straight line which is perpendicular to the upper guide rail 24. The rotation of the flight member 10 around the pivot 14 is restricted. Laura 19
Roll while maintaining contact with the lower surface 24a of the upper guide rail 24. Thereby, the flight member 1
0 is pushed inside the stirrer 5 or outside the stirrer 5 while maintaining a posture substantially perpendicular to a straight line connecting the abutment position of the roller 19 to the lower surface 24a of the upper guide rail 24 and the pivot shaft 14. The rail 21 is moved to the rear rail 21 without jumping out. Flight member 1
0 is closer to the rear surface side rail 21 than the front side (the pivot 14 side) in the moving direction of the endless strip 8 is.
Is gradually inclined such that the rear end side in the moving direction of the is the upper side. The roller 19 that has moved along the upper guide rail 24 smoothly moves to the front side of the rear rail 21 that is continuously provided to the upper rail 24 in the advancing direction of the agitator 5, and does not vibrate when moving. It does not happen.

The rollers 19 which move along the rear rails 21 are from the front side to the rear rail 21 in the traveling direction of the agitator 5.
The endless linear body 8 moves while rolling on the rear surface side rail 21. Further, since the straight line connecting the abutment position of the roller 19 moving along the rear surface side rail 21 to the rear surface side rail 21 and the pivot shaft 14 is perpendicular to the rear surface side rail 21,
The rotation of the flight member 10 about the pivot 14 is restricted, and the flight member 10 is fixed to the rear rail 2 of the roller 19.
1 is provided in the vicinity of the lower sprocket 7 while maintaining a posture that is substantially perpendicular to a straight line connecting the abutment position with respect to 1 and the pivot 14, that is, a posture that forms a rear surface that closes the rear side in the traveling direction of the agitator 5. And moves to the lower engagement transition portion 26. Thereby, for example, it is possible to reliably prevent the organic waste M that has been scraped up by the drive of the stirrer 5 and transferred to the rear side in the traveling direction of the stirrer 5 and accumulated, from entering the inside of the stirrer 5.

The upper surface of the flight member 10 which moves forward of the stirrer 5 in the traveling direction forms the rear surface on the rear side of the stirrer 10 in the traveling direction and is substantially vertical. The waste M is transferred to the rear side in the traveling direction of the stirrer 5 and generally falls naturally. The surface of the flight member 10 forming the rear surface is brought into sliding contact with the organic waste M deposited on the rear side in the traveling direction of the stirrer 5, so that the organic waste M attached to the flight member 10 is slid. Is scraped off.

The rail engaging portion 17 (specifically, the roller 19) of the flight member 10 that has moved along the rear surface side rail 21 is agitator of the front surface side rail 20 via the lower engaging transition portion 26. It is guided forward in the direction of travel.

A front guide rail 29 for guiding the front side rail 20 to the front side of the front side rail 20 in the traveling direction of the agitator 5.

The lower guide rail 28 is, specifically,
The movement locus of the pivot 14 due to the rotational drive of the endless strip 8 is curved along the inner side of a portion curved along the outer circumference of the lower sprocket 7. However, the curvature of the lower guide rail 28 is the same as the pivot 14
The movement locus is slower than the movement locus of No. 1 and gradually approaches the movement locus of the pivot 14 as it goes to the front side in the traveling direction of the stirrer 5. The roller 19 that has moved along the rear surface side rail 21 is smoothly moved to the lower guide rail 28 that is continuous with the rear surface side rail 21, and vibration occurs during this movement. Absent.

The roller 19 that moves to the pressure receiving member 27 on the curved inner surface side of the lower guide rail 28 is the agitator 5.
With the configuration of the lower guide rail 28 that gradually approaches the movement trajectory of the pivot 14 as it goes to the front side in the traveling direction, it is possible to slightly move with respect to the lower guide rail 28.
The flight member 10 is allowed to rotate slightly about the pivot 14 within a range corresponding to the movable range of the roller 19 with respect to the lower guide rail 28. For example, when the flight member 10 of the flight unit 9 that has moved along the lower guide rail 28 comes into contact with or is pressed by the organic waste M existing near the lower portion of the agitator 5, the flight member 10 is placed inside the agitator 5. Since it is slightly pushed in and forms a substantially continuous smooth agitator outer surface together with the fixed plate 13 and the closing plate 15, the contact resistance with the organic waste M can be reduced as much as possible, and the rotation resistance of the endless strip 8 is reduced. can do. Further, the gap between the flight member 10 and the closing plate 15 adjacent thereto can be made as narrow as possible, and the organic waste M can be prevented from entering the inside of the stirrer 5 through this gap. When the organic waste M does not exist near the lower part of the stirrer 5, the flight member 10 may open slightly to the outside, but a gap generated between the flight member 10 and the closing plate 15 adjacent thereto may be formed. It is easy to prevent the organic waste M from entering, or to prevent a gap from being generated at all.

A pressure receiving member 27 is provided along the lower guide rail 28.
The roller 19 that has moved to the vicinity of the lower guide rail 28
It passes through the clearance 30 secured between the pressure receiving member 27 side end portion 28a and the pressure receiving member 27 and exits from the lower guide rail 28. Pressure receiving member 27
Has a tapered outer surface of a shape that gradually goes to the outside of the stirrer 5 from the vicinity of the end 28a of the lower guide rail 28 toward the front side in the traveling direction of the stirrer 5. Therefore, the end portion 28a of the lower guide rail 28 on the pressure receiving member 27 side.
When the roller 19 reaches the pressure receiving member 27, the roller 19 moves along the outer surface of the pressure receiving member 27 with the movement of the flight unit 9 due to the rotational driving of the endless strip 8. Due to the outer surface shape, the endless strip 8 is pushed out on or near the movement locus of the pivot 14 due to rotational driving. When the flight member 10 of the flight unit 9 moving near the pressure receiving member 27 comes into contact with the organic waste M existing under the agitator 5, the roller 19 moves along the outer surface of the pressure receiving member 27, and the pivot 14 moves. As a result of being pushed to the locus or in the vicinity thereof, the flight member 10 is projected to the outside of the stirrer 5 by the rotation around the pivot 14, and the organic waste M existing under the stirrer 5 is scooped up. At this time, the organic waste M scraped up by the flight member 10 is sandwiched between the fixed member 13 and the flight member 10 which is projected to the outside of the stirrer 5 as the stirrer 5 moves toward the front side. Therefore, the stirrer 5 is surely moved to the front side in the traveling direction of the stirrer 5 and the leakage is prevented during the scooping, so that the excellent scooping efficiency is obtained.

[0032] In FIG. 1, the pressure receiving member 27 is specifically rotating a rotatably supported disc periphery SL before you pair <br/> the section rail engaging portion 17 (specifically Is rotated by abutting of the roller 19), so that it is less likely to wear due to follow-up rotation with the abutted roller 19, and
Even if wear occurs, this wear is almost evenly distributed over the entire circumference. Therefore, the function of the pressure receiving member 27 that projects the flight member 10 to the outside of the stirrer 5 due to the contact of the roller 19 is not easily impaired, and the length of the pressure receiving member 27 is long. The life can be extended. On the other hand, the rotation of the pressure receiving member 27, which is a disc, also makes it possible to prevent the roller 19 from being easily damaged and extend the life thereof.

When the flight unit 9 passes near the pressure receiving member 27, the roller 19 moves to the front guide rail 29.
Is moved along the stirrer 5 moving direction front, is induced to the front side rails 20, rises move the stirrer 5 moving direction front side of the front Gaware Lumpur 20. Hereinafter, while the flight member 10 is moved by the rotational drive of the endless strip 8, the flight member 10 is repeatedly driven up and down in the order described above, and the organic waste by the flight member 10 in a protruding state from the lower portion of the stirrer 5 on the front side in the traveling direction. The scraping of M, the transfer of the organic waste M from the upper part of the stirrer 5 to the rear side of the traveling direction, and the reduction of the rotational resistance of the endless strip 8 by the formation of the rear surface of the stirrer 5 by the flight member 10 moved to the rear side of the traveling direction are realized. To be done. It should be noted that the movement of the roller 19 from the front guide rail 29 to the front rail 20 is continuously and smoothly so that vibration does not occur during the movement.

In this waste decomposition processing apparatus 1, the stirrer 5 is used.
The rear surface formed by the flight member 10 being held in the direction along the movement trajectory of the pivot 14 by the rotational drive of the endless strip 8 on the rear side in the traveling direction of FIG. Since the load of the organic waste M piled up on the mixer can be converted into the thrust of the stirrer 5, a drive device for advancing the stirrer 5 becomes unnecessary, or a drive device with a relatively small output can be adopted. Therefore, cost reduction can be realized. Further, on the rear side in the traveling direction of the stirrer 5, the formation of the rear surface reduces the contact resistance between the flight member 10 and the organic waste M to reduce the rotation resistance of the endless strip 8, and the stirrer 5 from the rear side in the traveling direction. It is possible to prevent the organic waste M from entering the inside.

Further, in the stirrer 5 of the waste decomposition apparatus 1, the rail engaging portion 17 (roller 19) follows a substantially continuous series of movement paths formed by the rails 20, 21, 23, 24, 28 and 29. Is configured to smoothly move and to be rotationally driven repeatedly on the moving path, so that vibration is unlikely to occur. Therefore, spillage of the organic waste M from the flight member 10 during the transfer from the front side to the rear side in the traveling direction of the stirrer 5 can be significantly reduced, and in the end,
Fermentation of organic waste M, improvement of decomposition efficiency, fermentation of organic waste M, quality stabilization of products such as compost obtained by decomposition can be realized. Further, since the rotation speed of the endless body 8 can be improved by suppressing the vibration, the fermentation and decomposition efficiency of the organic waste M can be improved.

Further, the rails 20, 21, 23, 24, 2
The configuration in which the direction of the flight member 10 can also be changed by the roller 19 that moves in a series of movement paths formed by the pressure receiving members 27 and 8 and 29 is very simple, and the cost can be reduced. Further, on the rear side in the traveling direction of the stirrer 5, the contact position of the rail engaging portion 17 (specifically, the roller 19) with respect to the rear surface side rail 21 and the center of rotation of the pivot shaft 14 are on a straight line perpendicular to the rear surface side rail 21. The configuration in which the flight member 10 is held in the direction forming the rear surface (the direction parallel to the rear surface side rail 21) by being positioned at
Since it is not necessary to separately install a mechanism for preventing the rotation of the flight member 10 and the number of parts is extremely simple, the agitator 5 can be easily reduced in size, weight and cost.

The waste decomposition processing apparatus according to the present invention is not limited to the above-mentioned configuration, and various changes can be made.
The specific configuration of the pressure receiving member is not limited to a rotatable disc, and for example, instead of the pressure receiving member 27 in FIG. 1, a fixed cam or an end formed by extending the front guide rail 29 to the vicinity of the pressure receiving member 27. It is also possible to make the portion formed by the portion 29a function as a pressure receiving member. However, in view of the fact that the pressure receiving member generates a reaction force that pushes the flight member against the organic waste existing under the stirrer due to the contact with the rail engaging portion of the flight member, it has sufficient strength and abrasion resistance. Since abrasion resistance is required, it is advantageous to employ the rotatable disc in terms of meeting the required properties.
As the rail engaging portion provided on the flight member,
As described above, the structure is not limited to the arm 18 and the roller 19, and various structures can be adopted. For example, it is possible to employ a pin instead of the roller 19.

Therefore, the flight member can be held in a substantially parallel posture along the rear rail by a very simple structure, and the flight member can be projected rearward in the traveling direction of the stirrer, Since it is possible to prevent pushing, downsizing of the stirrer,
It has an excellent effect of easily realizing weight reduction and cost reduction. Moreover, the flight member is

According to the waste decomposition apparatus of the second aspect, the rail engaging portion of the flight member is guided by the horizontal maintaining rail provided in the upper engaging transition portion, so that vibration is generated extremely easily. It is possible to realize horizontal movement of the flight member above the stirrer with a configuration that is difficult to perform, and to prevent the scraped organic waste from falling from the flight member. Further, since it is easy to smoothly move the rail engagement portion from the horizontal maintenance rail to the rear surface side rail by the configuration that the vibration is less likely to occur via the upper guide rail, this also suppresses the vibration of the stirrer. This can be realized, and spillage of organic waste from flight members can be prevented.

According to the waste decomposition apparatus of claim 3, the rail engaging portion provided on the flight member moves along the lower guide rail provided at the lower engaging transition portion, so that the rail is engaged. Due to the engagement between the engaging portion and the lower guide rail, the flight member can be easily prevented from projecting to the outside of the stirrer even at the lower rear side in the stirrer traveling direction with a very simple and low-cost configuration. By preventing the flight member from projecting to the outside of the stirrer, it is possible to prevent the flight member from pushing down the organic waste in the lower portion of the storage tank, and thus it is possible to effectively reduce the rotational resistance of the endless strip.

According to the waste decomposition processing apparatus of the fourth aspect, the pressure receiving member is a disk rotatably supported,
Since it is rotated by the contact of the rail engaging portion of the flight member with the outer peripheral portion, wear of the pressure receiving member due to the contact of the rail engaging portion can be suppressed, and the life of the pressure receiving member can be reduced. It has an excellent effect that it can be extended.
